The basic, free file-syncing service, Ubuntu One Basic, will soon get a (beta) Windows client, while an upgraded Ubuntu One Mobile service will offer music streaming to iPhone and Android clients for $US3.99 per month, $US39.99 per year, and with a free 30-day trial. Users needing more than the basic 2GB can buy “20-packs” of storage for additional fees, and the cost goes to benefit the efforts behind Ubuntu and Ubuntu One storage. Does mobile music streaming of your own collection make Ubuntu One an appealing package?
